(Solved) System freeze on wight-gray screen.

I try for some 2 weeks to get my ipc 10.5.6 to work without much success..

I have Acer extensa 5620z laptop.
Intel Pentium Dual Core T2330 / 1.6 GHz ( Dual-Core )
Intel GMA X3100
1.5 MB ram

When i install ipc 10.5.6 i stay with vanylla kernel.
I use only needed drivers. Also i don't choose video driver.
After install all seems to work. But i have a lot of problems with restart.
Usually after restart, after wight screen with apple, screen goes to black for a second
and instead of normal start screen freeze on strange wight screen with gray lines on it.
I tried restart with -v or -x. Some times it worked, but mostly it don't.
I used another build - iatkos. The same result. It can work for a day and tomorrow
it simply freeze with that wight screen .Even if don't change anything.
Some times it booting wright and some times not.

I googled for identical problem with some answers, but can't find.

Anyone to help me?
